Steps to reproduce:

1. Compose new e-mail
2. Set the recipient emailadress to yourself.
3. Click Send
4. OnSend event we set internet message header, for example with code:

Office.context.mailbox.item.internetHeaders.setAsync(
    { "X-DO-Register-in-DMS": "true", "X-DO-ID": "9876" },
    (asyncResult) => {
        if (asyncResult.status === Office.AsyncResultStatus.Succeeded) {
          console.log("Successfully set headers");
          resolve();
        } else {
          reject("Error setting headers: " + JSON.stringify(asyncResult.error));
        }
      }
    );
 });

5. Find the sent message
   https://graph.microsoft.com/v1.0/me/mailFolders(%27sentitems%27)/messages/?$select=subject,internetMessageHeaders
6. Find the incoming message
   https://graph.microsoft.com/v1.0/me/mailFolders(%27inbox%27)/messages/?$select=subject,internetMessageHeaders

Issue
The internet header 'X-DO-ID' with value '9876' is only available on the received (incoming) message, but not on the sent message.

Note that the internet message header is visible on both the sent and received message if the eml is downloaded via Graph API, so the internet headers are available.

Expected
Both sent and received messages should contain the internet message headers if the messages are retrieved with:
https://graph.microsoft.com/v1.0/me/mailFolders(%27sentitems%27)/messages/?$select=subject,internetMessageHeaders

Background info
Eventually we want to receive the internet header messages in a rich notification as a webhook on the sent items folder.

Possible solution (Extracted from existing issue, might be incorrect; please verify carefully)

In Win32, all internet headers are saved to a MAPI prop while composing / in draft mode. They are converted to actual internet headers when sending the email. OWA doesn't care about the Win32 MAPI prop since they handle internet headers differently. If you do believe the consistency of internet header is important, you can always submit a feature request on our Tech Community Page with the appropriate label(s).

Hi @digiofficerobin,

Thanks for reporting this issue. Do you see this behavior in all platforms or only specific ones?

Hi @digiofficerobin,

I don't know what you mean with 'all platforms'. We use Office.js with Outlook online (New Outlook in the web browser) and Graph API as mentioned in the issue description.

Our objective is to automatically track sent emails and secure them in our Document Management System (DMS). Currently, Office.js only provides a 'before send' event, but not an 'after send' event. We aim to download a copy of the sent email. To facilitate tracking, we propose adding an internet message header to distinguish between emails that should be stored in the DMS and those that should not. If this should be done in another way we would like to hear that.
